MicronNav 200

USBL Tracking System

The MicronNav 200 system is the latest generation of UltraShort Base Line (USBL) positioning system from Tritech. Designed for small vehicles and diver supporting applications, the system benefits from a number of new features including  data transfer interleaved with USBL positioning, software integration into Google Maps™, smaller, more accurate USBL head and compatibility with the new MicronBattery Modem.

The system comprises a subsea MicronModem or Battery MicronModem, a surface USBL transducer with integral magnetic compass and pitch/roll sensors, a surface MicronNav 200 interface hub and bespoke operating software under control of a topside PC/laptop.

The MicronNav 200 uses spread spectrum acoustic technology. This provides a robust method for communication between the dunking transducers and the vehicle MicronModem/MicronBattery Modem. The USBL transducer can provide 180 degree hemispherical coverage below the transducer, which allows vehicle tracking in very shallow water. Omni-directional coverage is provided by the MicronModem and MicronBattery Modem.

The MicronModem is a stand-alone device which either responds to acoustic interrogation from the USBL head (transponder mode), or is triggered by RS232 / RS485 (responder mode) through the main port. The responder trigger can come either from the auxiliary port on a Tritech MicronSonar, or directly from the MicronNav 200 interface hub.
